YAY CAREFUL AND CONSIDERED ENGINEERING!
Thank you to all the people who have worked so hard on this.

This was an obvious idea since hard disk drives were created. Why didn't the massive performance improvement of zero track-to-track delay (taking into account rotational latency) for larger files, and better performance anyway, from having two complete sets of heads ever become a thing? Or did it, and it never made it to user-level compoinents?
A 240/230/220/110 switch usually indicates that a large iron-core transformer is being used, and the switch changes which tap on the primary is used, or for 110 V puts two (to better handle the doubled current) primary windings in parallel.
Not all switched-mode power supplies have an active power factor correction (PFC) stage which can work with a large range of input voltages. The ones that don't have active PFC have a switch to change between the input capacitors being wired in parallel (for 110 V) or series (for 230 V); they will of course only be rated for 200 V or so as there's no point using larger and more expensive capacitors. 230 VAC rectified gives about 325 V. Electrons with an excitement level of 325 V are partying too hard to be contained by a 200 V-rated cap, and the magic smoke and sparks escape.
What are the published uncertainties/error bounds/spread/confidence levels in PWC's predictions?
The report you appear to quote from,
says that the UK could fall from 9th to 10th or 5th to 9th place in the world by 2050, depending on the measure chosen.
Oh aye, lickin' the user input: first stage garbage collection. Next step were th' cleaning out th' next generation shite wi' owse toes, down th' sewers if we'se were lucky. T'urd generation garbage? That's only rich kids, wi' their fancy grammar 'n' some idea of a consistent accent.
Would a president of the USA push for an amendment to the constitution of the USA that requires a presidential candidate to take a sociopath test - and be declared as /not/ a sociopath - before being allowed to be their president? I'm sure the current president could pass, of course ;)
